The present invention relatesgenerally to ,.closures, yand more,particularly to Anovel improvements "1n the `construc- .tionandinstallation ofthe .SD-.called combination storm and screen doors. il

ICombinationdoors Iofthe character mentioned above .are very .well'known and .in .ever 'increasing popularity :In the very .greatmajority, these doors are `fabricated vshape or .theross-section patternof .these aluminum extrusionslhave, up -.to the, present time, followe'da somewhatqconventional form, .thatis,an.acceptedpattern which .thefabricators `have used ,to makegtheircombinationdoors. We have found,however, 4thatdoorsgmadefrom 'these old forms lof Vextruded sec.tious.arefdeticient in many respects.l In particular, .they `lack the, properlmeans .'.for `qliickjlyand sturdily ,hinging zsaidrrloors. Also, lackintheA meausieffective ,neatly `to t v.the ,.doorways finto which .thesaid `doors are tobe. installed.

Actually, it might well .be .said here that Hthe material-.that isthe..alun1iru1m-'is.v prima.rily chosenforllong .service ordurabilityrofthe door.-itself. "Itshoul'd follow, therefore, A.that .the ,fway of.constructing,thedoorlbe such as toprovide the y.means ,for .durableinstallation, commensurate with the` durability '.,o'f the` material of,the door.

.Itis a primeobjectottourtinvention toprov-ide 1a.generally improvedconstruction for a combination storm. and screen door.

Another ,object .of .ouriuvcntion .is to ,provide novel and improvedmeans for associating a storman'd screen door with the muck-:frame.scorn-monito'` the .installation of adoor. of thiszcharacter.

A further object of the inventionis .ft-ogprovideanovel methodOLdependably installing .a .door-'into anfexisting `framework of adoorway.

A still further object of our invention is to provide a novelarrangement for attaching hinges to a door.

A still further object is to provide a novel arrangement for sealing thebottom side of a door with the saddle piece of a doorway.

Other `objects and features of the invention will more fully appear fromthe following description and the appended claim.

In the said description, reference is had to the accom# panying drawing,in which:

Theintermediate vbuck-frame.mentione d above is-one that is 'formedlby way'of'an extrude'dstrip orbarn whose vcross sectional pattern resemblesthe letter Z.' Hence, strips -of this character are `commonlyloiownjinthefa-rt as Zlbars; the term appearing hereinafter. IItis `also tobeunderstood,that-in`thegretailibusiness of @doors lf'ithe character atissue,;the-ven'dor most always 4sells the installation servicewiththepro'duct, so that the 1price is'normally 'set so as to vincludethe item or the ,costof 'the time'required for .a man to .perform-the.service of installation. In many instances, `this service cost is acausefor unhappy business transactions, due v.principally to jthe lackof good standard designs Vfor-.doors ,of 'this .sort. 'Our door is thusdesigned to minimize y.past troubles .of installation. Moreover, .ourdooriincludes new provisions 'for improving the quality oftheinstallation. An .important feature of our door residesin thefactlhatthe said door may be sent out`for`its 'installation withoutpre-Avious determination of Whetherit'is to"be'hiugedso as to open. to theright ortothe left.

InFigure yl of the drawing, ourrdoor is .indicate`d generallyby thenumeral 10, and the associatingfbuck-,frame as 11. Thed-oor frame properincludes the two .vertical side members 10a and 10b, andthe topand,bottommembers 10cvaud 10d. rAll of these. frame members are. made 'fromhollow .aluminum-extrusions or bars., rthe -cross-section'of Which isclearlyshowninFigure 2. .There itis seen that the sectional patteruhas ahollow` ,core.12, anda conformity which includesaninnerbead l3ftogetherwith suitable tins 14and ,15. The latter are utilized tohold theinterchangeable, panels .used f in .doors vof thischaracter. 'The panelsand the arrangement thereof form,no. part .of the present inventionandneed not hereinbedisclosed in 4further details, exceptto pointoutthatsuch .panels .are located by wayofthe abovementionedns 14`andlvS. and {Iittedinto the spacesindicated inthe-drawing as ,16 and17. -.These two spaces, as is seen,.,are divided by meansof the.'mullionv piece 18. Justbelowthespace 17, .another .mullion piece v19is utilized so .as .tofurther divide the doorfand provide means -for.permanently securing tothe Llowerportion of the door.alrickplatelll.

The mullion pieces 18 and 19 are interlocked at each their ends fto theside members 10a and 10b, and further secured by means of screws in theusual manner. In turn the said side members are solidly secured to theirassociating top and bottom members 10c and 10d. For this purpose, We usecorner inserts 42, such as the one shown in dotted lines in the lowerleft hand corner of the illus-` trated door. These corner pieces haveright angularly extending arms 42a which tightly telescope into theopenings 12 -of two adjacent frame members; screws being used to retainthe parts together. Both the mullions 18 and 19 are made from anextruded shape 21 the crosssection of which is illustrated in Figure 5.The front portion 21a of the extrusion 21 is not only designed forappearance but also for utility. As seen in Figure 5, the extrusion 21has, at the junctions of its beaded portions 13 thereof and its curvedface 21a, a pair of anges 22` and 23. These extend in a sort ofcomplementary fashion so as to form :top and bottom recesses 22a and23a; the

top recess being deeper than the recess of the bottom, as may beobserved. The purpose of this arrangement is to provide means forattaching on to the door any decora-t.

forming the extruded shape, which is used to make the four side membersof the door, with a deep recess or channel in its outer edge, as is seenin Figure 2. The recess 25 is undercut as indicated, and, by way of thisarrangement, al1 four side members of the present door are outwardlychanneled in a manner to offer means for interlocking with said doorcertain elements of installation now to appear. In Figure 6, there isshown one of the hinge coupling elements 26, which are adapted to 'titin the abovementioned channel and serve to clamp the hinges 27 to thedoor 10. Also, in Figure 3, there appears another type of suchinsertable elements. This element is designated as 28, and its purposeis to cooperate in forming a seal for the said door with the saddlepiece 30 used in an installation of a door of the present type. Furtherdescription of the elements 26 and 28, together with their respectiveeffectiveness in the construction at issue, will appear more fully inconnection with the explanation of the manner of installing our door 10.

The buck-frame 11 is formed by way of the Z-shaped extruded stockaforementioned which form thereof the side sections 11a` 1lb and llc.The said stock has a facing flange 31, a web portion 32 and a backingflange 33. The latter has the customary longitudinally extend ing recess33a which is utilized to hold a weather strip 34, efective to seal thedoor to the buck-frame. In accordance with the present structure, weform the extruded Z-bar stock with an additional small flange or lip 35,as is shown in Figures 2 and 4. in order fully to make our inventionunderstood, a review of the parts will be had in connection with acomplete description of the manner of installing our door, this nowfollows:

As a first step, one of the vertical lengths 11a or 11b is provided withthe customary three `hinges-11b being selected as an example in thedrawing. This provision entails punching in its ilange 3l a set of threeslots 31a,

and notching the lip 35 thereof with notches 35a, as is clearly shown inFigure 4. In respective order, one side (the left side) of each of thehinges is then inserted through its respective slot 31a and is riveted,by way of its central hole, to the web portion 32 of the Zshaped length;it being understood that there are three holes in each side, as appearin Figure 4. With a length prepared in the manner above described, theinstaller will proceed to place the said length on to and along theouter edge of the portion 10b of the door, so as to spot the holes inthe left sides of the hinges on to the stock of the door forming thebottom of channel 25. The door is then drilled in correspondence withthe markings and, as a next step, the hinges are taken apart by removingthe pins 27a so that their left side may be attached to the door inaccordance with our invention. The attachment consists of inserting intothe channel 25 a set of three of the inserts or slugs 26 and of locatingthese slugs so that their holes 26a thereof will match the drilled holesin the door. This is followed by freely inserting the screws 37 throughthe hinges and through the slugs so that they may be threaded only intothe stock of the door. Such an arrangement, as will be understood, willcause the slugs to be drawn to the hinge parts and that both will beclamped solidly to the door. It is to be understood that before thescrews 37 are tightened the respective faces 2Gb of the slugs are notquite in Contact with the hinges. Now thevlength 11a may be permanentlysecured to the frame 38 of the doorway and the door mounted thereto byreassembling the hinges 27.

As previously stated, we provide a novel way of sealing the bottommember 10d of the door with the saddle piece 30. To this end, we slideinto the channel 25 of this bottom member the aforementioned insert orbar 28. In order to extend the sealing bar 28 fully across the bottornof the door, the lower end of both the members 10a yand 10b is slottedto correspond with the channel 25, as

will be understood. The bar 28 is provided with the 1ongitudinallyextending flange 28a which is designed in a manner to clinch with theweather strip 30a of the saddle piece 30, as is shown in Figure 3.

Having thus described our invention, by way of the particular embodimentherein illustrated, what we claim is:

In a door of the character herein described, in combination: a hollowframework forming said door; an undercut channel formed along the edgeof said framework; means for solidly securing hinges to said hollowframework, said means including individual pieces slidably insertableinto said undercut channel and movable to any position for coupling with.said hinges; said pieces having holes matching holes in the hinges;said pieces and said hinges being clamped to the edge of Said door byscrews that are passed freely through both the pieces and the hinges andthen threaded into the stock of the door at the bottom of said channel.
